<p>1,185,580. Capacitor circuits for a space discharge apparatus. ROBERT BOSCH ELEKTRONIK und PHOTOKINO G.m.b.H. 3 Oct., 1968 [23 April, 1968], No. 46883/68. Heading H2H. [Also in Divisions G1 and G2] The control circuit for photographic flash apparatus of Specification 1,185,579 is modified in that the D.C. operating voltage for the photoelectric integrator is derived from the flash tube firing capacitor which on firing shares its charge with a larger capacitor to provide the D.C. voltage.</p> |
